pH calculation
Thread Content
At room temperature, to a 320 L solution of A with a pH of 6.80, 30 g/L of NaOH solution is added to adjust the pH to 7.50. What is the volume of NaOH solution required?
It’s not even worth considering. How can it be calculated without even saying what the materials are? Acidic salts, strong acids, and weak acids are all different. There’s also the isoelectric effect and such... Then one might not know anything at all and just start calculating the pH value right away.
The answer is above; the original poster had better organize the known conditions properly~~~
Agree with the view from Floor 2. With only the pH value available, and no specific acid or base value data, it is not possible to calculate the requirements for adjusting the system’s pH using a strong base. Buffer systems, reaction systems, simple ideal systems, and complex mixed systems – there is a huge difference between them.
